In fact you don't even need to have a filesystem on it. GRUB installs its second part on that empty partition, and the first part (which is in the dummy MBR) should locate it by its physical address. I think you may be confusing this with the "boot partition" mentioned in the book, which is actually something quite different. It is a normal partition with a filesystem on it that is used to contain kernels when you are multibooting LFS with other Linuxes. The team recommend having this common boot partition for all your systems and mounting it on /boot in each of them.
